摘要
采用光束位移法测量了透明玻璃板的折射率 ,分析了折射率的公式和实验误差处理公式 .结果显示 :实验的准确性主要取决于折射角 θ,并且 θ在 2 0°～ 35°范围内 ,实验的效果较好 .
The refraction index of transparent glass-plate was measured with ray-displacement method, formulas of the refraction index and experimental error were obtained by theoretical analysis. The results shows: experimental accuracy is mainly determined byθ, and experimental effect is good in the range of 20°~35°.
